I found a couple YouTube videos of the steps/methods for the flora and Earl (I don't have my books with me for the jig and Scotch measure right now)

For the flora (SDTA):youtu.be . . .
For the under twelves, watch the girl on the right, everyone else is the girl on the left.

Main differences between methods I've found just looking quickly:
- the curtsey has to be on the 1/2 point, not ball.
-as mentioned the point in the introduction goes to 4th and then opens to 4th int on count one of the hop brush beat beat.
-as mentioned in the first step there is no round the leg movement.
-other than the obvious turning steps, there is no body turn. No shoulder leads no nothing. PDB step I'm looking at you!
-from the SDTA book, the beauty of the dance comes from its simplicity and flourishes such as sharp round the leg movements are discouraged. This really shows up in the backstep and travel with the "soft spring" to second.

For the Earl (UKA) I couldn't find one magical video with all the options.

Under twelves, watch the girl on the right, 12-16 watch the girl on the left.

Over sixteen: the girl on the left does the second step, the girl on the middle the third step. Don't watch them for the first step though, just the two middle steps.

Other than the note listed in the first step about the change of feet, I couldn't find any major differences... Except:

-the curtsey can be done on the ball of the left foot OR 1/2 point!

I'd love to hear any other notes and I'll go through the Scotch measure later.

Side note: I just YouTube searched public videos. If any of them are someone you know/minds having them up I'll switch them out.

So many changes this year! For the flora, the second step (syncopated hop) must be done travelling in the circle, still on the half point and travelling towards 4th intermediate. Also in the backstep and travel it is not a backstep but a ronde movement following the shuffles so the working foot does not come into contact with the supporting leg. Another thing to add with the step is that when the working foot is brought into third after the travel to second, it is placed on the half point, not the full point. Some changes in the Earl: the first break in the first step (this step only!) must be danced without a change in the first assemble, so it's danced as- Assemble, out Assemble (foot in front) change, change. In the over 16s the second step, double treble, must be danced travelling in an oval shape. The third step, hop and travel is danced with minimal travel on the bouree while turning. As for the last step, it has to be danced with no leaps, even for boys! All this was told to us at the BATD conference but I might be missing a few things as these are still new steps. Good luck with 2018 everyone!

It might help if you think of the oval as a hot dog shape. That's how we always thought of it! I find the movements lend to a hot dog shape pretty naturally - if you're used to moving on the double trebles that is.
